"Over at Digiconomist, a Bitcoin blog and analysis site, owner Alex de Vries reported last week that the Bitcoin Energy Consumption Index, an measure of the energy used to mine the digital currency every year, reached 30.59 terawatt-hours. This still leaves out electricity used by other parts of the Bitcoin pipeline, like ATMs, de Vries told me in an email."
Bitcoin's price spike is driving an extraordinary surge in energy use.

Malice may attack it,
ignorance may deride it,
